At various times of the year, for one reason or another, the spiders come out. I have no idea what kind of spiders they are or why they do what they do. But I do know what happens after they make their periodic invasions: unsightly, hard-to-remove stains on gelcoat, mostly near faux planking grooves, seams, and crevices. While other cleaners (even bleach) may fail to address the problem, Star-brite’s new Spider & Bird Stain Remover quickly dissolves spidery messes. Moreover, the stuff is nontoxic (contains no bleach) and does not remove polish or wax.
